Not many women are aware of the fact that their diets could be affecting their brains. According to recent studies, a deficiency in healthy fats, particularly omega-3 fatty acids, may make women more prone to developing Alzheimer’s disease later in life.
Cumulative medical evidence indicates that low levels of healthy fats, especially DHA and EPA, increase women’s susceptibility to Alzheimer’s, says Dr Sachin Adukia, Senior Consultant Neurologist, Dr L H Hiranandani Hospital in Powai, Mumbai. “These omega-3 fats aren’t just a trendy health claim, they are vital for the brain, supporting cell membranes, communication between neurons, and controlling inflammation”, Dr Adukia tells Moneycontrol. He adds that without them, our brain cells may struggle to send signals efficiently, leaving the brain more vulnerable to damage.
Furthermore, research shows that women with Alzheimer’s often have lower concentrations of omega-3-related lipids in their blood compared with healthy women. “Men, by contrast, do not exhibit the same disparity, hinting at a sex-dependent risk factor.” Dr Adukia informs, adding, “Lower lipid levels in women were also linked with poorer performance on memory and cognitive tests, signalling that the impact isn’t just theoretical—it’s measurable.”
Reason why women are more vulnerable:
Post-menopausal hormonal changes appear to play a major role. These shifts can alter lipid metabolism, reducing the brain’s ability to access essential fatty acids. Add to that the fact that women generally live longer than men, and the lifetime risk of dementia naturally rises.
Dr Adukia shares modern lifestyle factors adding to the risk, suggests prevention tips:
- Low-fat or restrictive diets that inadvertently cut out omega-3s
- High consumption of processed foods, which replace good fats with harmful ones
- Sedentary lifestyles and rising stress levels
He notes, “While the link between omega-3 deficiency and Alzheimer’s is strong, we cannot yet claim causation. Large-scale clinical trials are needed to confirm whether boosting omega-3 intake will prevent or delay the disease.”

Practical steps to protect your brain:
- Include oily fish salmon, mackerel, or sardines in your meals
- Snack on walnuts, flaxseeds, and chia seeds
- Consider omega-3 supplements of advices by your doctor
- Maintain an active lifestyle and reduce processed foods

FAQs on the Role of Omega-3 in Alzheimer’s Risk:
1. What are omega-3 fatty acids?
Omega-3 fatty acids are essential fats that play a crucial role in brain health, including DHA and EPA.
2. How do omega-3 fatty acids affect Alzheimer’s risk?
Low levels of omega-3 fatty acids can impair brain function and increase the risk of Alzheimer’s by affecting cell membranes, neuron communication, and inflammation.
3. Are women more affected by omega-3 deficiency than men?
Yes, studies show that women with Alzheimer’s often have lower concentrations of omega-3-related lipids compared to healthy women, while men do not exhibit the same disparity.
4. Can increasing omega-3 intake prevent Alzheimer’s?
The link is strong, but large-scale clinical trials are needed to confirm if increasing omega-3 intake can prevent or delay Alzheimer’s.
